Abstract
La présente invention a pour objet un procédé de validation d’un diagnostic de déviation de la richesse comportant les étapes de pilotage d’une fonction de régulation de la richesse (E23) par un adaptatif de correction, de diagnostic de déviation de la richesse consistant en cas de détection d’une fin de défaillance pour un adaptatif, à valider la fin de défaillance d’un adaptatif précédent en fonction d’un test opéré sous critère de conditions similaires avec ledit point de référence. Selon l’invention, le procédé comporte en outre la sélection (E26) dudit point de référence en fonction de la valeur de déviation de richesse de chaque correctif temporaire, et en ce que le test sous critère de conditions similaires est opéré en comparant chaque correctif temporaire avec le point de référence.
